Mr. W.F.Kirby exhibited a dwarf male specimen of Polyommatus Tcarus (Alexis) 

 measuring only S^ lines in expanse of wings. This pigmy was captured by Mr. Kirby 

 about the 20ih of July last at the suit marsh ut Hove, near Brigliton, and except in its 

 diminutive size did not present any Frtriaiion from the ordinary form of the insect, 

 which was then very common in that locality. 



Mr. StaintoD exhibited a liighly-ma{;nitied coloured drawing of the larva of 

 Laverna subbislrigella, logether vviih pods of Epilobiuni montaniim in which the 

 larvae had fed, and which had, in consequence, a somewhat stunted and deformed 

 growth : the habit of the insect was discovered at Wiesbaden, and Mr. Barrett had 

 this year detected the larva; at Haslemere, where the imago had previously been 

 captured. 



Mr Stainton (on behalf of Mr. Dorville) exhibited a specimen of Caradrina cubi- 

 cularis having a number of red Acari symmetrically arranged upon its wings. 



Mr. Stainion mentioned that he had this ye.ir noticed an unusual abundance of 

 Chelifers on the legs of house-6ies; the natural place for Chelifers would seem to be 

 amongst vegetation, and Dr. Hagen was of opinion that they attached themselves to 

 flies only for the purpose of locomotion ; with this he could not agree, for the Clielifer, 

 according to his observations, never quitted a fly to which it once attached itself, and 

 the fly was powerless to get rid of it. Ou one occasion be had seen a fly with three 

 Chelifers on one of its legs. 



Mr. M'Lachlan exhibited both sexes of ^Eshna borealis (Zellerstedl), taken by 

 him at Rannoch in June last. This dragon-fly was previously known as British by a 

 single example only, captured many years since in Scotland by Mr. Wilson, and now 

 in the collection of De Selys Longchamps. 



Mr. M'Lachlan also exhibited Sialis fuliginosa (Pictet, Brauer), a species new to 

 Britain, and taken at Rannoch. There were but two European species of this genus, 

 and biith had now occurred in this country. 



Mr. M Lachlan also exhibited two new British Trichoptera ; one, a Rhyacophila, 

 from the neighbourhood of Edinburgh, allied to, if not identical with, R. ferruginea 

 i^Hagpu) ; the other a Slenophylax, from Uaunoch, for which he proposed the name 

 of S. infumatus. 



Mr. S. Stevens exhibited a box of Coleoptera, part of a collection made in Damara- 

 land by the well-known traveller Mr. Andersson ; amongst them were a Phryssoma, a 

 Manticora (latipennis?), several species of Goliathus, G. Burkei, G. Layardi, and aa 

 Eudicella, n. sp., allied to E. Smilhii. 



Prof Wesiwood gave an account of a visit to the Exhibition of Insects and Insect- 

 products, which was opened at Paris on the 15th of August last. He mentioned par- 

 ticularly some bee-hives which were sold for If. 25c. each ; and an octagonal bar-hive, 

 which was so constructed as to be capable of division into two distinct hives: a prnpot 

 of the silk-products, he mentioned that the silk-merchants were beginning to import 

 Ailanthine as an article of commerce, and that certain experiments had recently been 

 made at Toulouse with a view to test the quality of the Ailantbus wood ; the tenacity 

 and density of Ailantbus (as given by three experiments) and of elm and oak (as given 

 by seven experiments) were comparatively as follow: —
